Ford guys - 5.0 or 3.5 eco boost?

[typhoon916]

I can't say anything about towing but my 20 5.0 f150 got 21 mph when I went too Utah 3 weeks ago

I have a 2019 F150 5.0 and have nothing but good things to say. Better mileage than I expected 16-18 in town and 21-22 highway. Plenty of juice in everything I've done. The big reason I went for the 5.0 is that I realized if the engine on the 3.5 (or 2.7) ever need almost ANYTHING both turbos have to come off..... that is like 8-10 hours of labor from the kick off. Nope for me.

They're excellent for towing but not so good for snowy forest service roads. Ecoboost has the added complexity of a turbo, which is probably worth it. It's best to chain up early with a diesel.
